OVEN-SLIDE.

SIECIFICATION forming part of Letters Patent No. 429,380, dated June 3, 1890.

Application filed March 4, 1890. Serial No. 342,569. (No model.)

To all whom it may concern.-

Be it known that l, HARRY T. GILBERT, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Oven-Slide, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved oven-slide which is simple and durable in construction, very effective in operation, and self opening and closing.

Theinvention consists of a hinged extension-plate provided with a cam-edge, a vertically-arranged shaft provided with a cam-arm adapted to engage the said cam-edge, and an arm secured on the said shaft and operated on by the closing of the stove-door.

The invention also consists of certain parts and details and combinations of the same, as will be hereinafter fully described, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front view of the improvement as applied, the stove-door being in section. Fig. 2 is a transverse section of the same on the line 00 m of Fig. 1. Fig. 3 is a front view of the improvement as closed. Fig. 4 is a transverse section of the same. Fig. 5 is a perspective view of the shaft, and Fig. 6 is a transverse section of the slide proper in a closed position. I

The stove A, of any approved construction, is provided with the usual baking oven B, adapted to be closed by a door 0. On the side walls of the baking-oven B are arranged sets of guideways D, in which are fitted to slide horizontally and transversely the slides E, of which there may be any desired number, according to the number of sets of guideways D.

On the under side of each slide E and at the front end are arranged downwardly-extending lugs F, on which are pivoted the brackets G, supporting an extension-plate H, which, when thrown downward into a horizontal position, is in line with the respective slide E, and which also projects in this position beyond the front open end of the oven B. The brackets G are so' arranged that when the extension-plate H is swung downward the rear ends of the brackets abut against the under side of the front end of the slide E, so as to hold the extension-plate in a horizontal position.

On one end of each extension-plate H is formed a cam I, adapted to be engaged by a cam-arm J, projecting from a shaft K, mounted to turn in suitable hearings in the stove A and arranged vertically at one side of the bakingoven B. On this shaft K is secured a second arm L, which extends in line with the camarm J, and is adapted to be actuated by a block N, secured on the inside of the stovedoor 0.

In order to ease the inward and outward sliding of the slides E, friction-rollers O are arranged on the sides of the baking-oven B, under each of the slides, at the front end, as is plainly shown in the drawings.

The operation is as follows: WVhen the several slides E are in position in the bakingov en B and the door O is open, then the extension-plates H are in their lowermost horizontal position, so as to form an extension to the said slides E as they project in front of the baking-oven B. When the extensionplates H are in this position, the arm' L and cams J of the shaft K extend toward the front, as plainly shown in Fig. 2, and when the operator now closes the door 0 the block N on the latter comes in contact with the arm L, so that the shaft K is turned and engages by its cam-arms J the cam-edges I of the several extension-plates H, whereby the latter are swung upward into a vertical position, thereby permitting a full closing of the door O. IVhen the operator again opens the door O, the extension-plates H swing into a downward position, as previously described, by their own weight.

It will thus be seen that by opening and closing the door O the extension-plates H of the slides E are automatically opened and closed. The shaft K is so arranged that the slides can be readily taken out whenever desired.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In an oven-slide, the combination, with a vertically-arranged shaft provided with a cam-arm and adapted to be turned by the clos- TO by the oven-door and provided with a camarm adapted to engage the earn-edge of the said extension-plate, and an arm pro eetmg from the said shaft and adapted to he engaged by a block secured on the stove-door, substantially as shown and described.
